A study was conducted to determine the efficacy of a high protein diet with or without exercise to improve muscle strength, body composition, and lower extremity physical function (LEPF) in older inactive overweight/obese women after weight loss.
The research conducted by Evans and colleagues is published in the journal American College of Sports Medicine
Obesity has a negative effect on the lower extremity physical function (LEPF) in older adults. Exercise and a high protein diet can positively and independently affect body composition, muscle strength, and LEPF during weight loss. In older women, the potential interactive effects have not been well characterized.
- High protein diet
- High protein diet plus exercise
- Conventional protein control diet plus exercise
During weight loss, exercise is important to preserve strength and enhance LEPF. However, when a high protein diet is combined with multicomponent exercise, no influence on body composition, muscle strength, or LEPF were seen.
